POTATO-KILLER.

neeasao.

To all whom it may concern.

Be it known that I, FRANK L. NAU and HARRY D. NAU, citizens of the United 7 States, residing at Crookston, in the county of Polk and State of Minnesota, have invented certain new and useful Improvements in Potato-Hillers, of which the following is'a specification.

Our invention relates to hillers, may be adapted to any pulling power for the purpose of drawing the hiller longitudinally of a row of plants, for pilingdirt up around the plants.

An important object of our invention is to provide a device of the above mentioned character including means whereby various heights of earth may be'piled up around plants.

Another object of our invention is to provide a device of the above mentioned character including means whereby piles ofearth of various widths may be piled upv around plants.

Another object of our invention is to provide a device of the above mentioned character which is strong, durable, inexpensive to manufacture and eflicient in practice.

Other objects and advantages will be apparent during the course of the following description. r

In the accompanying drawings forming a part of the description and wherein like numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevation of our invention, the dotted lines showing the adjustment made for a higher hill of earth.

Fig. 2 is a front view of our invention, and

Fig. 3 is a sectional View of the same taken on the line 33 of Fig. 1.-

In the accompanying drawings wherein is shown a preferred embodiment of our invention, the numeral l designates an arch structure, which is circular in cross section, and has its free ends oppositely disposed at right angles to the arch, as at 2, then inclined slightly downward to form the axle sections 3. Harrow disks 4.- a-re adjustably mounted upon the incline axle sections and are clamped in any desired position by the slid able collars 5, carrying the usual set of screws, and are adapted to be mounted upon the incline axle sections and clamp against the opposite faces of the harrow disks.

' The hiller is drawn by means of a pair ofelongatedrods 6, carrying an opening at each end thereof. *These'rods extend forwardlyof the hiller and have the rear ends received on the angular portion 2 of the arch and held in position by the collars 7, which are similar to the collars 5. The opening 8 in the forward end of the drawing rods '6, is for the reception of a bolt to secure the hiller to the drawing power. A pair of bars 9, each of which is provided with a longitudinal slot 10, are adapted to be pivotally connected at the lower ends'with the drawing rods 6, at a point intermediate the ends of the rods 6, by meansofbolts 11.

These bars 9 are arranged at an angle to the arch and drawing rods, and are adapted to be adjustably connected to the arch, by means of the bolts 12 passing through the arms of the arch, adapted to operate in the slots 10. Nuts are secured on the outer threaded end of the bolts 12, and Washers are interposed between the bars 9 and the arms of the arch. The brace rods 13 are .pivotally connected to the drawing rods 6 by means of the bo-lts'll, and extend forwardly at an angle to the drawing rods 6 to be attached to the drawing power. These brace rods are adapted to be secured to the drawing power by the openings 1d in the forward ends thereof, co-acting with bolts.

shown in Fig. 2.

Various heights of hills will be thrown up by simply loosening the nuts on the bolts 12 and swinging the arch either forward or backward. It will be seen that by arranging the bars 9 at an angle to the arch and rods 6 it requires comparatively no exertion to make the angular adjustments of the arch. Various widths of hills may be thrown up by adjusting the disks along the inclined axle sections.

It is to be understood that the formof our invention herewith shown and described is to be taken as a preferred example of the 95. 'mentupon the axle sections, as more clearly size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the sub-' joined claims.

Having described our invention we claim:

'1. A potato hiller including an arch, axle sections arranged at an angle to said arch,

disks adjustably mounted thereon, means for drawing the hiller, and slotted rods connected to the arch and drawing means for adjusting the angle of the arch.

V 2. A potato hiller including an arch, axle sections arranged at an angle thereto, disks adjustably mounted on said axle sections, means for drawing the hiller, slotted rods connected to the arch and drawing means at an angle, and means arranged upon the arch to cooperate with the slotted bar for holding the archat various angles.

3. A potato hiller including an arch, disks carried by said arch, drawing rods connected .to said arch, and rods pivoted tosaid drawing rod and adjustably connected to said arch.

4. A potato hiller including an arch, disks carried by said arch, drawing rods connected to said arch, rods pivoted to said draw- 'ing rods, and adjustably connected to said arch, and brace rods pivotally secured to the said drawing rods. 5. A potato hiller including an arch having its free ends bent outwardly thereof in opposite directions then downwardly to provide axle sections, disks adjustably mounted upon said axle sections, means for drawing the hiller, and slotted rods connected to the arch and drawing means for adjusting the angle of the arch and the axle sections.

In testimony whereof we affix our'signatures in presence of two witnesses.
